High Strength The high strength of steel per unit of weight means that structure weights will be small. This fact is of great importance for long-span bridges, tall buildings, and structures having poor foundation conditions.   b. Uniformity The properties of steel do not change appreciably with time as do those of reinforced concrete structure.   c. Elasticity Steel behaves closer to design assumptions than most materials because it follows Hooke’s law up to fairly high stresses. The moments of inertia of a steel structure can be definitely calculated while the value obtained for a reinforced concrete structure are rather indefinite.   d. Permanence Steel frames that are properly maintained will last indefinitely. Research on some of the newer steels indicates that under certain conditions no p
